Me and a homie recently started a tomb of annihilation campaign and were frolicking around port nyanzaru getting information before we headed into the jungle. This all went to hell in a few days when we got convicted for committing the most horrific homicide the city had yet seen (we got jumped by cultists, then as good followers of Sotek tore their hearts out in an offering). So currently we are in the sewers with no clue where we are going and what we will encounter. So what should we be expecting and any sewer survival tips for two saurus and a carnosaur?
You three should just live in the sewers from now on. You can survive off vermin and random creatures/people who venture into your domain. With time there arise legends and myths of giant reptilian predators who lurk the undercrofts and drainage of the city.
A young one, not full size, but it’s still a massive sewer I mean, this is an awesome idea but we still got stuff to do on the continent outside of the sewers although eating vermin could work
You might additionally stop some random invasion like Felix and Gotrek did in Nuln (and Nuln's sewers)
The key is to sync with the Dungeon Master. He is a friend to help you tell a story, not an enemy to be bested. There are lots of things a giant fantasy sewer can be used for. A side quest, a dungeon, a home base. I have no idea for survival tips because sewers can hold almost anything.
